That's the probability that both events will happen, possibly even at the same time. I think it's called the 'joint' probability.

In theoretical probability, the probability is determined by an assumed model (for example, the normal distribution). (compare with empirical probability)
Yes.Yes.Yes.Yes.
Yes, probability can be expressed as a percent. It is common to express probabilities as a percentage, which is calculated by multiplying the probability by 100. For example, if the probability of an event is 0.25, it can also be expressed as 25%.
Let X and Y be two random variables.Case (1) - Discrete CaseIf P(X = x) denotes the probability that the random variable X takes the value x, then the joint probability of X and Y is P(X = x and Y = y).Case (2) - Continuous CaseIf P(a < X < b) is the probability of the random variable X taking a value in the real interval (a, b), then the joint probability of X and Y is P(a < X< b and c < Y < d).Basically joint probability is the probability of two events happening (or not).
A joint probability can have a value greater than one. It can only have a value larger than 1 over a region that measures less than 1.
Ball-and-socket joint is an example of triaxial (or multiaxial) joint.
That's the probability that both events will happen, possibly even at the same time. I think it's called the 'joint' probability.
The joint probability function for two variables is a probability function whose domain is a subset of two dimensional space. The joint probability function for discrete random variables X and Y is given aspr(x, y) = pr(X = x and Y = y). If X and Y are independent random variables then this will equal pr(X =x)*pr(Y = y).For continuous variables, the joint funtion is defined analogously:f(x, y) = pr(X < x and Y < y).

The probability of event A occurring given event B has occurred is an example of conditional probability.
A suture is an example of an immovable joint called a synarthrosis.
